Tesla's driver-assist software sped in 55% of Brussels 30 km/h zones tested.
Johanna.be, a Brussels nonprofit campaigning for pedestrian and cyclist safety, drove about 400 km on the city's slow streets over three days in July using Tesla's FSD (Supervised).
Tesla sells the software as Full Self-Driving, Electrek reported on 24 September.
In 55% of the 30 km/h zones, it exceeded the limit and averaged 44 km/h. In most cases, the system read the limit incorrectly and displayed 50 km/h.
On residential shared streets limited to 20 km/h, it went over the limit on 42% of the streets tested. It also repeatedly tried to overtake cyclists where Belgian rules forbid it.
Citing WHO data, the study says a pedestrian hit at 44 km/h is nearly six times more likely to die than one hit at 30 km/h.
Belgium approved FSD on 10 June. A Flemish government spokesperson said the system is "learning" and drivers remain "100% responsible". Tesla did not respond to Electrek's request for comment.
If a company car on driver assist breaks the limit, where does your fleet policy put the risk?
